EasyEDA update – online circuit design
Posted in Uncategorized
We posted about EasyEDA years ago. They’re going strong. They’ve updated the software, and added an online, free Gerber viewer. They’ve also branched out and sell components.

The breadboard you didn’t know you wanted
Posted in Hardware
It’s a microcontroller built into a breadboard. Actually, TWO microcontrollers. Both are Arduino-compatible. ATmega16U2 and ATmega328P.
It comes in both black, white, and pink because style matters.
P.S. The bottom side is filled…
ReSpeaker – Funded, still-available kickstarter for adding voice control to your project
Posted in Hardware
In an earlier post, we discussed how surprisingly useful well designed voice control can be. There are open source software solutions for voice control, but they aren’t integrated with hardware, and there wasn’t really a kit to help one get started. Now there is.
Here’s an open…
Tibbo Project System – modular microcontroller
Posted in Hardware
Tibbo makes modular microcontrollers, with plug-in modules for I/O ports (e.g. DB9), relays, sensors, digitizers, etc. They have different sizes, the largest of which is available as a Linux version.

Ripple noise on PMTs in 2-photon imaging
Posted in Tips
Andrew Lim wrote in to discuss strategies on dealing with ripple noise in 2-photon imaging systems, particularly when using resonant scanners. He writes:
This isn’t so much a tip as a problem with resonant two-photon scopes…
Sanworks’ open source behavior devices and pulse generator
Posted in Hardware
Sanworks has a whole series of devices for behavior experiments. Everything is open source and well documented. You can also pay them to assemble the devices if you choose.

Leonardo Lupori and Raffaele Mazziotti are two fellows in lab of the excellent Tommaso Pizzorusso. They have developed an intrinsic signal optical imaging rig and are sharing all of the materials. Here’s their web site…
3D printed electronics

It’s been promised for a while now, but someone has to do the hard work to make it happen. That inevitably involves some pretty pitiful looking stepping stones on the way to the promised…
TriggerScope for imaging system device control
Posted in Hardware
Austin Blanco has designed and built an open-source system for controlling complex imaging systems called TriggerScope. It’s highly customizable out of the box, and both the firmware and software are open.
Lightfield imaging – development kit from Lytro
Posted in Hardware
Lytro is releasing a development kit for their light field camera. That’s nice, but it pretty expensive. And we’ve been able to buy light field cameras for technical uses for years.
What’s special…
Raspberry Pi oscilloscope
Posted in Hardware
One can use a Raspberry Pi as a highly customizable 20 MHz scope with this cute little BitScope Micro. (about 120 euros, from the OE store)
They have their…
MultiSIM BLUE – free circuit design software
Posted in Hardware
MultiSIM BLUE is yet another free, SPICE-based electronics simulator– this one is linked into the MOUSER catalog, to streamline parts sourcing. Also includes PCB design tools.

Resonant scanning with ScanImage 5
Posted in Hardware
ScanImage 5 supports resonant scanning with a wide range of hardware. So custom rigs can add resonant scanning pretty easily, while sticking with ScanImage for acquisition.
